Definitions
- the present disclosure is directed to combination therapies of tigecycline and warfarin and methods of administration of tigecycline and warfarin.
- Tigecycline (9-(t-butyl-glycylamido)-minocycline, TBA-MINO,
- (4S,4aS,5aR,12aS)-9-[2-(tert-butylamino)acetamido]-4,7-bis(dimethylamino)- i ⁇ a. ⁇ .Sa.e.H . ⁇ a-octahydro-S.IO. ⁇ . ⁇ a-tetrahydroxy-I .H-dioxo ⁇ - naphthacenecarboxamide, is a glycylcycline antibiotic and an analog of the semisynthetic tetracycline, minocycline.
- Tigecycline is a 9-t-butylglycylamido derivative of minocycline, formula (I):
- Tigecycline developed in response to the worldwide threat of emerging resistance to antibiotics, has expanded broad-spectrum antibacterial activity both in vitro and in vivo.
- Glycylcycline antibiotics like tetracycline antibiotics, act by inhibiting protein translation in bacteria.
- Tigecycline is active against many antibiotic-resistant gram-positive pathogenic bacteria, such as methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant enterococci (Eliopoulos, G. M. et al. 1994. Antimicrob Agents Chemother 38:534-41 ; Fraise, A. P. et al. 1995. Journal of Antimicrobial Chemotherapy. 35:877-81. [erratum appears in J Antimicrob Chemother 1996 May;37(5):1046]; Garrison, M. W. et al. 2005. Clinical Therapeutics 27:12-22; Goldstein, F. W. et al. 1994.
- Tigecycline may be used in the treatment of many bacterial infections, such as complicated intra-abdominal infections (clAI), complicated skin and skin structure infections (cSSSI), Community Acquired Pneumonia (CAP), and Hospital Acquired Pneumonia (HAP) indications, which may be caused by gram- negative and gram- positive pathogens, anaerobes, and both methicillin- susceptible and methicillin-resistant strains of Staphylococcus aureus (MSSA and MRSA). Additionally, tigecycline may be used to treat or control bacterial infections in warm-blooded animals caused by bacteria having the TetM and TetK resistant determinants.
- clAI complicated intra-abdominal infections
- cSSSI complicated skin and skin structure infections
- CAP Community Acquired Pneumonia
- HAP Hospital Acquired Pneumonia
- tigecycline may be used to treat or control bacterial infections in warm-blooded animals caused by bacteria having the TetM and TetK resistant
- tigecycline may be used to treat bone and joint infections, catheter-related bacteremia, Neutropenia, obstetrics and gynecological infections, or to treat other resistant pathogens, such as VRE, ESBL, enterics, rapid growing mycobacteria, and the like.
- Hlavaka, et al. U.S. Patent No. 5,529,990 discloses a method of treating or controlling bacterial infections in warmblooded animals comprising administering a pharmacologically effective amount of a 7- substituted-9-(substituted amino)-6-demethyl-6-deoxytetracycline, of which tigecycline is a member of the genus described.
- 5,529,990 also discloses a method of treating or controlling bacterial infections in warm-blooded animals caused by bacteria having the TetM and TetK resistant determinants comprising administering a pharmacologically effective amount of a 7-substituted-9-(substituted amino)-6-demethyl- 6-deoxytetracyciine, of which tigecycline is a member of the genus described.
- U.S. Patent No. 5,529,990 is incorporated herein by reference in its entirety.
- Tigecycline may be prepared by lyophilization and formulated, for example, compounded in the hospital pharmacy, for reconstitution as an IV solution. Tigecycline will frequently be administered simultaneously with other diluents and drugs. Thus, in one embodiment, tigecycline should not interact with or adversely affect the administration of the other drugs when the drugs are given together.
- warfarin is 3-( ⁇ -acetonylbenzyl)-4-hydroxycoumarin and is a racemic mixture of the R- and S-enantiomers.
- Crystalline warfarin sodium is an isopropanol clathrate. Its empirical formula is C19 H15 NaO4, and its structural formula may be represented by the following:
- the objective of anticoagulant therapy is to decrease the clotting ability of the blood so that thrombosis is prevented, while avoiding spontaneous bleeding.
- Warfarin is, for example, indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, and pulmonary embolism; for the prophylaxis and/or treatment of the thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement; and to reduce the risk of death, recurrent myocardial infarction, and thromboembolic events such as stroke or systemic embolization after myocardial infarction.
- warfarin shows great interindividual variation, as does the toxic concentration; warfarin has been described as having a narrow therapeutic index.
- Any change in this concentration, as a consequence of a pharmacokinetic (PK) interaction with other drugs used concurrently, may therefore lead either to a clinically important reduction in the pharmacological response or to an increase in the incidence of unwanted toxic effects.
- PK pharmacokinetic
- the tetracycline class (e.g., tetracycline, chlortetracycline, demeclocycline, minocycline, oxytetracycline, methacycline, and doxycycline), a widely used antibiotic class, is known to have an adverse interaction with warfarin sodium ("warfarin”) generally causing an increase in international normalized ratio (INR) in comparison to administration of warfarin alone.

- Venous blood samples (3 mL) for determination of warfarin concentration in serum are collected on study days 1 through 8 of period 1 and study days 5 through 12 of period 2 at the following times: within 2 hours before sodium warfarin dose administration, and at hours 0.5, 1 , 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 144, and
- Venous blood samples (7 mL) for tigecycline PK determination in serum are collected during period 2 of the study at the following times: study day 1 (predose - collected 2 hours before tigecycline administration), at hour 12 (before the evening dose of tigecycline), and on study days 4 and 5 immediately before tigecycline morning administration and at 0.5, 1 , 1.5, 2, 3, 4, 6, 8, and 12 hours after the 8 AM dose.
- Tigecycline blood samples are collected from an indwelling catheter or by direct venipuncture. If a catheter is used for blood collection, then approximately 0.5 mL of blood is to be discarded before collecting the sample in a tube that did not contain any anticoagulant.
- the total amount of blood collected from each subject is approximately 640 mL.
- Blood for warfarin analysis is gently mixed with the warfarin in the collection tube and the tube is placed on ice immediately.
- the tubes are centrifuged within 15 minutes of collection at approximately 1000g for about 10 minutes.
- the separated plasma is then transferred to a watertight, labeled polypropylene tube and stored frozen in an upright position at -70 0 C or colder until shipped.
- Blood tubes for tigecycline analysis are placed immediately on ice until a clot forms.
- the tubes are centrifuged at approximately 100Og for about 10 minutes in a refrigerated centrifuge.
- the serum is collected and transferred into a labeled polypropylene tube and stored in an upright position at -70 0 C or colder until shipped.
- Concentrations of tigecycline in serum is determined by sensitive and specific liquid chromatography methods with tandem mass spectrometer detection (LC/MS/MS), and concentrations of R(+)-warfarin and S(-)-warfarin in plasma is determined by a separate LC/MS/MS procedure.
- the performance of the tigecycline and warfarin assays during the analysis of the serum and plasma samples from this study is summarized in Tables 1 , 2 and 3.
- the steady-state tigecycline serum concentration data for each subject is analyzed by using empirical, model-independent pharmacokinetic methods.
- the peak concentration (C max ) and the time to peak concentration (t max ) are taken directly from the observed data.
- the area under the concentration-time curve over 1 dosage interval (AUC 0- i2 h ) is calculated by using the log-trapezoidal rule for decreasing concentrations and the linear-trapezoidal rule for increasing concentrations.
- Systemic clearance (Cl) is calculated as dose/AUC, and it is presented both corrected and uncorrected for body weight.
- the single-dose R-warfarin and S-warfarin plasma concentration data for each subject also are analyzed by using empirical, model-independent pharmacokinetic methods.
- the apparent terminal-phase disposition rate constant ( ⁇ z ) is estimated by a log-linear regression of the last 2 to 5 observed serum concentrations that are determined to be in the log-linear elimination phase by visual inspection.
- the prothrombin time (expressed in seconds and INR) is measured at predose and at 0.5, 1 , 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 96, 120, 144, and 168 hours after each single-dose warfarin administration.
- the peak INR (INR ma x) and the time to peak INR are taken directly from the observed data.
- the area under the INR vs time curve over the 168-hour observation interval is calculated using the linear trapezoidal rule.

- AUC 0- i 2h area under the concentration time curve during the dose interval 0 to
- the mean steady-state tigecycline systemic clearance and exposure (C max , C-i 2h . and AUC) are within 10% of the mean values for tigecycline monotherapy. Additionally, the 90% confidence limits of the geometric mean parameter ratio are all within the strict bioequivalence interval criteria of 80% to 125%. Thus, coadministration of warfarin does not alter the PK profile of tigecycline.

- FIG 2 Mean (SE) Plasma S-Warfarin Concentrations in Healthy Subjects Receiving a Single Oral Dose of Warfarin 25 mg Alone and With Concurrent Multiple IV Doses of Tigecycline 50 mg Every 12 Hours
- the mean INR 013x values are 10% lower following administration of the combination treatment, and the mean INR AUC 0- i 68h values are unchanged (See FIG 3: Mean (SE) Prothrombin Time INR in Healthy Subjects Receiving a Single Oral of Warfarin 25 mg Alone and With Concurrent Multiple IV Doses of Tigecycline 50 mg every 12 Hours.
- the INR max and INR AUC 0-168h meets the strict bioequivalence
- Warfarin coadministration does not alter the PK profile of tigecycline.
- administration of the therapeutic regimen of tigecycline increased the exposure (AUC) of R-warfarin and S-warfarin by 68% and 29%, respectively, but this increase in AUCs does not significantly alter warfarin's anticoagulant profile (measured by INR).
- AUC exposure
- No safety-related concerns are identified in healthy subjects after the administration of a single 25-mg oral dose of warfarin alone, multiple 50-mg IV doses of tigecycline, and the combined multiple-dose administration of 50 mg IV tigecycline and a single 25-mg oral dose of warfarin. Therefore, no dosage adjustment is warranted with coadministration of tigecycline and warfarin.
- the proper level of anticoagulant activity should be monitored whenever patient treatment is altered, such as initiating treatment with another drug.
